Serial No. 268,408,

When a warp becomes exhausted in a loom and it is necessary to piece a new war onto the same, as with the use of a warp twistingin machine, if the piecing operation is done in the loom the latter must stand idle in the meanwhile. Hence it has been proposed in the Calleson et al. Patent No. 810,711 to provide a frame or portable support in which the harness could be mounted and then removed from the loom and placed in a frame where the piecing operation could be done independently of the loom, which was then available to continue weaving when furnished with another warp, harness and reed. But

there was no provision in that case for transporting from the loom with the old warp the fallers and faller-sup orting or terminal bars of a stop-motion w ere such was used in the loom and hence had to be taken into account the same as the harness and reed. It is therefore the principal object of this invention to provide a portable sup orting means whereby the fallers and said ars as well as the harness may be transported from the loom, as for the purpose indicated. A further object is to provide a supporting means by which the elements of each group of parts comprising on the one hand the shafts or frames of harness and on the other the fallers and said bars, and the two such groups with respect to each other, may be held and maintained by the supporting means in a definite and orderly arrangement until they are re-incorporated in the loom.

1 is the frame, 2 the take-up roller, 3 the warp-beam, 4 the reed on the batten or lay 5, 6 the suitably hung harness-frames, 7 the lease-rods an 8 (generally) the warp stopmotion mechanism of a loom. This mechanism as usual is shown arranged back of and spaced from the harness, or so that the fallers thereof are between the lease-rods, the support for the movable parts thereof in fact appearing as carrying the latter. Said mechanism, following a well known construction, comprises with the rows of fallers 9, terminal bars marked 9a in Figs. 1 and 4:

side elevation of and each penetrating a row of fallers and comprising strips 10 and 11 (one mounted in and insulated from the other) forming terminals of an electric circuit and insulated from each other; brackets 12 each secured to a side of the loom frame and together forming the said support, each bracket being notched to receive the terminal bars; and a bridge or gate 13 having an insulating piece 130*. carrying a metal shoe 13b equipped with springcushioned contacts13c to bear on the strips 11 and hold the terminal bars firmly the brackets, each ate being adapted to swing back (dotted lines, Fig. 1) to permit any terminal bar to be removed when occasion requires, being normally locked down by a pivoted kee r 14; in operative condition one terminal 0 an electric circuit (not shown) containing electro-magnet-ic means for causing actuation of some device to stop the loom is connected to the shoe 137), as at'13ac, and the; other terminal to some part of the (metal) loom frame 'to-which a (metal) bracket 12 is secured, and when all the warp threads are taut and unbroken they support the fallers, which they respectively straddle, elevated clear of strips 10, so that the circuit, otherwise complete, is open between 10 and 11, but if a faller is allowed to fall and close the circuit across lO11 the circuit is energized to cause the stopping. The support afforded by the brackets 12 receives, so as to be upwardly removable therefrom when the gates 13 are swung back, the two lease-rods 7.

That section of my supporting means which is adapted for carrying the harness is constructed as follows: There is an elongated rectangular block 15 having arms 16 and 17 projecting rigidly therefrom, arm 17 pro jecting from one end of the block and arm 16 from that broad face thereof herein taken as the underneath face. On the arm 17 is slidable a jaw 18 having a thumb screw 19 to bind against the arm. In the block and parallel with arm 16 and outwardly thereof with respect to jaw 18 is a vertically slidable member comprising a rod 20 having at its lower end a head 21 with a keyhole slot 21a therein, the enlarged end of the slot being up; this member is held in the block at any position to which it may be adjusted by a thumb screw 22. Parts, 15, 16 and 17 form an L- shaped member with respect to the arm 16 of which jaw 18 is cooperative as a clamp. This clamp may be fitted over the tops of a group of harness frames as shown in Fig. 2 and thereupon made to clamp them together so that the section of my supporting means and the group of harness frames become in effect a unit. (The grooves 15a shown in the underneath face of the block in Figs. 3 and 6 are present simply to accommodate the screws 6a which usually protrude from the harness frames 6). It will be noted that the arm 16 of the L-shaped member projects sufficiently downward so as to bear against the lower of the two (upper and lower) horizontal slats 6b of the harness frames. The section of my supporting means now being described includes two of the L-shaped members and the described parts associated therewith.

That section of my su porting means which is adapted for carrying the terminal bars is constructed as follows: A cradle is provided comprising two counterpart end members or brackets 23, having notches 23a for receiving the terminal bars, and a bar 24 rigidly connecting said brackets and arranged at what I term the backs of the two brackets and near their bases; this cradle has, pivoted to each bracket so as to movem a vertical plane, a bridge or gate comprising a piece 25, having a pivoted hook 26 to engage a stud 27 on the bracket normally holding it down in the position shown by full lines, Fig.8, and a piece 29 under and spaced from the shoe 25 and cushioned against upward displacement by a spring 30 which is interposed between suitable shoulders on the piece 25 and one of the stems 31 which confine the shoe to vertical movement with respect to said piece. At the back of each'bracket pro jects a headed stud 32 which is adapted to engage in the keyhole slot 21a of the head 21, being thus in effect a hook. Spanning the two brackets 23 of the cradle and at the front thereof and below the notches is preferably a bar 33 removably held in place by spring clamps 34.

In the use of my supporting means, that section thereof which is to carry the harness is first made to clamp the same as described and as shown in Figs. 2 and 3. Then, having removed the lease-rods 7 and substituted lease-cords or the like, the bridges or gates of the stop-motion mechanism are swung back as shown in dotted lines in Fig. 1, thus permitting the removal upwardly of the terminal bars and the fallers carried thereby from the brackets 12, whereupon that section of my supporting means which is to carry said bars and the fallers, with bar 33 thereof removed so as not to interfere with the fallers and with the gates of its brackets 23 in the open position (dotted lines, Figs. 1, 4 and 8), is elevated from below until the terminal bars are all seated in the notches 23a and, having returned said gates to their closed positions and locked them therein by the hooks 26 (all the bars being now firmly held by the spring pressed shoes 29), the unit now comprising the assembled section and bars and-fallers is bodily transposed to and secured in rigid relation to the other section, to wit, by entering the hooks 32 in interlocked engagement with the heads 21. The mentioned cradle, being U-shaped in plan or having bar-supporting portions 23 rigidly connected with each other by bar 24 and also having a space between said portions for reception of the fallers, facilitates removal of the terminal bars without disturbance of or possibly injuring the fallers in th act of introducing it to the position for supporting the bars. The two sections, with the harness on the one hand and with the terminal bars and fallers on the other and with the warp, may now be removed bodily or as a unit from the loom and hung on the gibbet-like hangers 35 shown in Fig. 2 in position for performing the twisting-in or other operation; usually the reed will, without separating it from the warp, be also removed and for removing the warp, if the piece being woven is completed, the same may be cut, or if it is not completed the cloth beam may also be removed from the loom. I not only thus provide for removal of the harness and the terminal bars and fallers from the loom together, but my supporting means therefor also serves to keep them while they are out of the loom in both an orderly and very compact and permanent arrangement. ()1? course, after the cradle has been made to receive the terminal bars and before that section of my supporting means which carries the latter and the fallers is transposed to the other section, the bar 33 is replaced as a support from which the. tail ortion of thewarp may hang.

In this specification the example-of stopmotion assumed is of the electro-magnetic type; the invention, however, is applicable to any stop-motion mechanism in which the fallers are arranged on one or more bars, wires or the like (herein termed bars) which are removable and when removed carry the fallers with them; and by fallers I mean to include detectors of any kind which are held by the warp threads out of but normally urged, by gravity or otherwise, into position for causing the stopping.

The connection between the two sections is actually such that either may serve as the carrying member for the other, for instance, the harness-supporting section performing that function when the entire structure is suspended on the hangers 35 and the other section when said structure is being transported from or-to the loom. Having thus fully described my invention, what I claim is:

1. Means to remove from a loom the stopmotion fallers and the bar carrying them and also the harness and contained warp including separate sections, one for supporting said bar and the other for supporting the harness, said sections having means to connect them as a unit so that either may serve as the carrying member for the other.

4. Means to remove from a loom the stop motion fallers and the bar carrying them and removable from the loom transversely of itself including a carrying cradle for the bar till detachable therefrom and having end portions rigidly connected with each other and also having a space between said portions for reception of the fallers, said end portions having means on which the ends of the bar are detachably engaged.

5. Means to remove from a loom the stopmotion, fallers and the bar carrying them and removable from the loom transversely of itself including a rigid carrying cradle for the bar detachable therefrom and formed substantialiy il-shaped in pian, the terminal portions of the cradle being adapted to support said bar and receive in the space between them the fallers.

6. Means to remove from a loom the stopmotion fallers and the bar carrying them and removable from the loom transversely of itself including a rigid carrying cradle for the bar detachable therefrom and formed substantially U-shaped in'plan, the terminal portions of the cradle being adapted to support said bar and receive in the space between them the fallers, and said cradle also including a warp-supporting bar traversing said terminals and movable out of traversing relation to the terminals to permit the fallers to be received in said space.

7. Means to remove from a loom the stopmotion fallers and the bar carrying them and removable from the loom transversely of itself including a carrying cradle for the bar having bar-supporting portions rigidly 'connected with each other and also having a space between said portions for reception of the fallers and also including means to clamp the bar to the cradle.

8. Means to support in pendent position the harness frames of a loom consisting of a clamp adapted to receive the top portions of the frames and comprising relatively adjustable members and means for fixing said members in adjusted relation, at least one of the members havin a downwardly extending rigid portion to ar against the exposed face of one of the end frames so clamped.

9. Means to clamp the harness frames of a loom comprising a rigid L-shaped member having one arm substantially horizontal and, adapted to traverse the top edges of the frames and the other arm depending and adapted to bear against the exposed face of one of the end frames, in combination with a clamping member slidable against the' exposed faoe of the other end frame on the first arm.

10. In combination, portable means to support and transport from a loom a harness frame thereof, and portable means to support and transport from the loom the bar for supporting the stop-motion fallers of the loom and such fallers, said means having means to interlock them together for transportation from the loom as a unit.

11. Means to remove from a loom the stopmotion fallers and the bar carrying them and also the harness and contained warp including a bar-carrying section and a harnesscarrying section, the latter projecting rigidly upwardly from the former-and having means elevated above the same to suspend the har ness and also being detachable from the former.
